Is this a USAF rebuild, or one of the firefigher mods that was talked
about a while ago?

Looks like USAF # still on the tail, so that may answer the question...

There's no firefighter mods of the Thunderpig; they're all still active. It
might be a rebuild, as they go through a lot of structural stress in their
'daily lives'. There is an update program and this might be one of the
first of that.
